General Information

ANNUAL MEETING AND VOTING INFORMATION

This Proxy Statement is being furnished in connection with the solicitation by the Board of Graphic Packaging Holding Company of proxies to be voted at the 2025 Annual Meeting of Stockholders (the "Annual Meeting"). This Proxy Statement and the enclosed proxy card or notice of availability on the Internet will first be sent on or before April 7, 2025 to the Company's stockholders of record as of the close of business on the Record Date. References in this Proxy Statement to the "Company," "Graphic Packaging," "GPHC," "we," "us," and "our" or similar terms are to Graphic Packaging Holding Company.

Outstanding Shares

As of the close of business on the Record Date, there were 301,754,281 shares of the Company's common stock outstanding and entitled to vote. Stockholders are entitled to one vote for each share held on all matters to come before the Annual Meeting.

Who May Vote

Only stockholders who held shares of the Company's common stock at the close of business on the Record Date are entitled to notice of and to vote at the Annual Meeting or any adjournment thereof.

How Proxies Work

The Board of Directors is asking for your proxy. By giving the Board your proxy, your shares will be voted at the Annual Meeting in the manner you direct. If you retua signed proxy but do not specify how you wish to vote your shares, your shares will be voted "FOR" the election of each of the Director nominees, "FOR" the approval of the ratification of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm, "FOR" the proposal to approve the compensation paid to the Company's named executive officers, and "FOR" the amendments to the Company's Charter documents to implement a simple majority vote. Your shares will not be voted with respect to the proposal to elect each Director annually. The proxyholders will vote shares according to their discretion on any other matter properly brought before the Annual Meeting.

If for any reason any nominee for election as Director is unable or declines to serve as a Director, discretionary authority may be exercised by the proxyholders to vote for a substitute proposed by the Board.

If the shares you own are held beneficially in street name by a bank or brokerage firm, such firm, as the record holder of your shares, is required to vote your shares according to your instructions. To vote your shares, you will need to follow the directions your bank or brokerage firm provides to you. Under the rules of the NYSE, if you do not give instructions to your bank or brokerage firm, it will still be able to vote your shares with respect to certain "discretionary" items, but will not be allowed to vote your shares with respect to certain "non-discretionary" items. In the case of non-discretionary items, the shares will be treated as "broker non-votes." Banks and brokerage firms are allowed to exercise discretionary voting authority for beneficial owners who have not provided voting instructions only with respect to Proposal 2 set forth in this Proxy Statement and not with respect to any other proposal to be voted on at the Annual Meeting.

General Information

How to Vote Your 401(k) Plan Shares

If you participate in the Company's 401(k) Savings Plan or the Company's Hourly 401(k) Savings Plan (the "401(k) Plans"), you may give voting instructions as to the number of share equivalents held in your account as of the Record Date to the trustee of the 401(k) Plans. You provide voting instructions to the trustee, Fidelity Management Trust Company, by completing and returning the proxy card accompanying this Proxy Statement. The trustee will vote your shares in accordance with your duly executed instructions if received by 11:59 p.m. EasteTime on May 16, 2025. If you do not send instructions, the trustee will not vote the number of share equivalents credited to your account.

You may also revoke voting instructions previously given to the trustee by filing either a written notice of revocation or a properly completed and signed proxy card bearing a later date with the trustee no later than 11:59 p.m. EasteTime on May 16, 2025. Your voting instructions will be kept confidential by the trustee.

Quorum

In order to carry out the business of the Annual Meeting, there must be a quorum. This means that at least a majority of the outstanding shares eligible to vote must be represented at the Annual Meeting, either by proxy or in person. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of votes present at the Annual Meeting for purposes of calculating whether a quorum is present.

Votes Needed

The Director nominees receiving the largest number of votes cast are elected, up to the maximum number of Directors fixed by the Board to be elected at the Annual Meeting. As a result, any shares not voted, whether by abstention, broker non-vote or otherwise, have no effect on the election of Directors, except to the extent that the failure to vote for a particular nominee may result in another nominee receiving a larger number of votes. However, under the Company's Corporate Governance Guidelines, a nominee for director who receives a greater number of votes "withheld" than "for" is expected to tender his or her resignation to the Board promptly following certification of the election results. The Nominating and Corporate Governance Committee will consider any resignation tendered under this policy and recommend to the Board whether to accept or reject it. The Board will act on such resignation within 90 days following the certification of election results. A Director who tenders his or her resignation will not participate in the Nominating and Corporate Governance Committee's recommendation or in the Board's decision regarding whether to accept such resignation. Approval of Proposals 2, 3, and 4 requires the affirmative vote of holders of a majority of the shares present in person or by proxy and entitled to vote on such matter at the Annual Meeting. Approval of Proposal 5 requires the affirmative vote of 75% of the holders of the shares present in person or by proxy and entitled to vote on such matter at the Annual Meeting. An abstention with respect to these matters will have the effect of a vote against such proposal and broker non-votes will have no effect, as broker non-votes are not treated as shares entitled to vote.

Changing Your Vote

Shares of the Company's common stock represented by proxy will be voted as directed unless the proxy is revoked. Any proxy may be revoked before it is exercised by sending an instrument revoking the proxy or a proxy bearing a later date to the Company's Corporate Secretary. Any notice of revocation should be sent to: Graphic Packaging Holding Company, 1500 Riveredge Parkway, Atlanta, Georgia 30328, Attention: Corporate Secretary. Any proxy submitted over the Internet or by telephone may also be revoked by submitting a new proxy over the Internet or by telephone. A proxy is also revoked if the person who executed the proxy is present at the Annual Meeting and elects to vote in person. If you hold your shares through an account with a brokerage firm, bank or other nominee, please follow instructions from such firm to change or revoke your proxy.

Attending in Person

Only stockholders, their designated proxies and guests of the Company may attend the Annual Meeting. If your shares are held beneficially in street name, you must bring an account statement or letter from your brokerage firm or bank showing that you are the beneficial owner of shares of the Company's common stock as of the Record Date in order to be admitted to the Annual Meeting.

OVERSIGHT OF ESG MATTERS

ESG matters inform our decisions about how we operate and grow our business, protect our environment and support our employees. In recognition of the importance of ESG matters to the Company, we believe that a two-tieredlevel of oversight provides the best structure to integrate consideration of ESG risks and opportunities into our overall business strategy and help us meet the changing demands of all our stakeholders - stockholders, customers, employees and communities. Our Board of Directors is responsible for the oversight of our sustainability strategy, governance standards, goals and performance and has assigned principal oversight of our sustainability policy and practices to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee considers current and emerging social and environmental trends, as well as major legislative and regulatory developments and other public policy issues that may impact our business operations or stakeholders. The Committee also reviews the Company's policy and practices for consistency with its ESG commitments, including goals, performance metrics, and public reporting and makes recommendations to the Board and management. In addition, oversight of governance matters such as enterprise risk management and cybersecurity risk, as well as oversight of controls and procedures related to reporting ESG data, are assigned to the Audit Committee, while oversight of a range of human capital and social matters related to the effective recruitment, development and retention of talent necessary to support the long-term success of the Company is the responsibility of the Compensation and Management Development Committee.

In August 2024, the Company published its 2023 ESG Report, which is available on the Company's website at www.graphicpkg.com/sustainability/sustainability-reporting. In addition, in 2024 the Company was recognized for the third year in a row by Fortune as one of the world's most admired companies, announced its ambition to achieve net zero greenhouse gas emissions by 2050, and reaffirmed its commitment as a participant in the UN Global Compact.

COMPANY CULTURE AND ENGAGEMENT INITIATIVES

Graphic Packaging works to enable a safe, engaged, and customer-focused culture, and has a solid record of delivering outstanding results for its customers across the globe. As a leading innovator in consumer packaging, a deep understanding of the widest range of consumers is essential to the success of our designs and product execution for our customers. As such, the Company seeks to recruit and retain talented employees whose perspectives and experience are broadly representative of the consumers our customers serve.

Similarly, strong relationships with the communities in which the Company operates have a substantial impact on hiring costs, retention rates, employee engagement, operating performance and safety. The Company therefore seeks to build and maintain strong and capable teams broadly representative of those communities. The Company believes that its recent safety performance is among the best in the industry, and considers employee engagement to be critical to maintaining and improving upon that level of safety performance.

The Compensation and Management Development Committee of our Board of Directors annually reviews the processes and practices related to talent and engagement to ensure the equitable treatment of all employees, and alignment with the Company's strategic objectives.

Our employees play a crucial role as well, and we rely on their insights and feedback to assess our culture and identify areas for improvement. In 2024, we conducted a global employee engagement survey in partnership with Gallup, resulting in 87% of our employees sharing their voice - a significant increase in participation compared to the previous year. The results of this survey were shared with our entire employee population, and action plans have been created at the local level in facilities around the globe to identify and execute opportunities to enhance the employee experience. The Company has a number of initiatives underway to drive employee engagement higher.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The Board recognizes that Related Party Transactions (as defined below) can present potential or actual conflicts of interest and create the appearance that Company decisions are based on considerations other than the best interests of the Company and its stockholders. In March 2007, the Board of Graphic Packaging Corporation (the publicly-traded predecessor to the Company, "GPC") delegated authority to the Audit Committee to review and approve Related Party Transactions, and the Audit Committee has adopted a Policy Regarding Related Party Transactions.

Corporate Governance Matters

The Policy Regarding Related Party Transactions defines a "Related Party Transaction" as any transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) in which (a) the aggregate amount involved will or may be expected to exceed $120,000 in any fiscal year, (b) the Company is a participant, and (c) any Related Party (as defined below) has or will have a direct or indirect interest, other than an interest that arises solely as a result of being a director or beneficial owner of less than 10% of another entity. The policy defines a "Related Party" as any (a) person who is or was since the beginning of the last fiscal year an executive officer, director or nominee for election as a director of the Company, (b) any beneficial owner of more than 5% of the Company's common stock, (c) an immediate family member of any of the foregoing, or (d) any firm, corporation or other entity in which any of the foregoing is employed, is a principal or serves in a similar position, or has a beneficial ownership of more than 5%.

The Policy Regarding Related Party Transactions provides that the Audit Committee shall review all of the material facts and circumstances of all Related Party Transactions and either approve, ratify or disapprove of the entry into the Related Party Transaction. In determining whether to approve a Related Party Transaction, the Audit Committee will take into account, among other factors it deems appropriate, whether the Related Party Transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances, the benefits to the Company, the extent of the Related Party's interest in the transaction, and if the Related Party is a director or a nominee for director, the impact on such director's independence. The policy provides that certain Related Party Transactions, including certain charitable contributions, transactions involving competitive bids and transactions in which all stockholders receive proportional benefits, are pre-approved and do not require an individual review by the Audit Committee. You may find a copy of the Policy Regarding Related Party Transactions on the Company's website at www.graphicpkg.com/corporate-governance/governance-documents.

GOVERNANCE DOCUMENTS

The Company will provide printed copies of the charters of the Audit Committee, Compensation and Management Development Committee and Nominating and Corporate Governance Committee, as well as the Policy Regarding Related Party Transactions, the Code of Business Conduct and Ethics and the Corporate Governance Guidelines to any person without charge upon request.

Proposal 1 - Election of Directors

The Company's Board of Directors currently has ten members divided into three classes, with one class being elected each year for a three-year term. The three nominees standing for election as Class III Directors are: Ms. Brlas, Mr. Hagemann and Mr. Alessandro Maselli. Ms. Rhinehart, currently a member of the Board, is not standing for re-election.

If elected, each Class III nominee will serve three consecutive years with the term expiring in 2028 and until a successor is elected and qualified. The election of the Director nominees is by plurality vote, which means that the three nominees receiving the highest number of affirmative votes will be elected. Under the Company's Corporate Governance Guidelines, any nominee who receives a greater number of votes "withheld" than "for" votes in an uncontested election is expected to tender to the Board his or her resignation as a Director promptly following certification of the election results. The Nominating and Corporate Governance Committee will then consider such resignation and recommend to the Board whether to accept or reject it and the Board will act on such resignation within 90 days following the certification of election results.

If at the time of the Annual Meeting, any of the nominees identified above is unable or unwilling to serve as a Director for any reason, which is not expected to occur, the persons named as proxies will vote for such substitute nominee or nominees, if any, as shall be designated by the Board.

Set forth below is certain information regarding the Director nominees and each of the incumbent Directors whose term will continue after the Annual Meeting, including the particular experience, qualifications and skills that led the Board to conclude that the Director nominee or incumbent Director is qualified to serve as a Director of the Company. There are no family relationships among any Directors or executive officers of the Company.

CRITERIA FOR POTENTIAL DIRECTORS

The Company's Board is responsible for selecting nominees for election as Directors by stockholders and for filling vacancies on the Board. The Nominating and Corporate Governance Committee is responsible for identifying and recommending to the Board individuals for nomination as members of the Board and its committees and, in this regard, reviewing with the Board on an annual basis the current skills, background and expertise of the members of the Board, as well as the Company's future and ongoing needs. This assessment is used to establish criteria for identifying and evaluating potential candidates for the Board. However, as a general matter, the Nominating and Corporate Governance Committee seeks individuals with significant and relevant business experience who demonstrate:

DIRECTORS' SKILLS MATRIX

Proposal 1 - Election of Directors

The Nominating and Corporate Governance Committee also recognizes the importance of selecting directors from a range of backgrounds and professions to provide the Board a wealth of experiences and perspectives to inform its decisions and enhance its cognitive diversity. Consistent with this philosophy, the Nominating and Corporate Governance Committee evaluates the ability of a potential director to contribute to the Board by leveraging a broad range of experiences, as well as the potential director's ethnic, gender, generational and racial diversity. Currently, the Board has two continuing female directors and one ethnically diverse director.

The Nominating and Corporate Governance Committee considers candidates recommended by its members and other Directors, as well as those identified by a third-party search firm retained to assist in identifying candidates. The Nominating and Corporate Governance Committee will also consider whether to nominate any person recommended by a stockholder pursuant to the provisions of the Company's By-Laws relating to stockholder nominations as described in "Stockholder Proposals and Nominations" below. The Nominating and Corporate Governance Committee uses the same criteria to evaluate proposed nominees that are recommended by Directors or a search firm as it does for stockholder-recommended nominees.

BOARD RECOMMENDATION

The Board believes that voting for each of the three nominees for Director selected by the Board is in the best interests of the Company and its stockholders.The Board recommends a vote "FOR" each of the three nominees for Director.

COMPENSATION OF DIRECTORS

Annually, WTW benchmarks the amount and type of compensation paid to the Company's non-employee Directors against that paid by other companies in the Industry Specific Peer Group used for comparing executive officer compensation (as described in "Compensation Discussion and Analysis-Peer Group and Market Data"), as well as against a large published survey of non-employee director compensation across a wide range of industries and company sizes. The goal is to set non-management Director compensation at roughly the mid-point of compensation paid by companies of similar size in similar industries. The Nominating and Corporate Governance Committee reviews the benchmarking materials and approves and recommends all non-management Director compensation changes for approval by the full Board of Directors.

The following table sets forth information regarding the compensation of the non-employee Directors of the Company who served in 2024.

Director Compensation

Proposal 1 - Election of Directors

On May 24, 2023, the Board of Directors revised the compensation program for non-employee directors as shown below. No changes were made to the compensation program for non-employee directors during 2024.

COMPENSATION HISTORY

Cash retainers and fees are payable in quarterly installments. The annual equity grant is payable in May of each year in shares of the Company's common stock with a value of approximately $160,000 on the date of grant. The Company does not pay Board or committee meeting fees, but does reimburse all Directors for reasonable and necessary expenses they incur in performing their duties as Directors.

In July 2020, the Board of Directors approved a non-qualified deferred compensation plan for Directors (the "Directors NQDCP") that allows the Directors to defer receipt and taxation of their annual compensation commencing in 2021. The Directors NQDCP has the same investment fund choices as the Company's non-qualified deferred compensation plan for senior employees, but also allows the Directors to defer their cash and equity compensation into a Company stock fund. Messrs. Aghili, Hagemann, Scarborough and Ms. Wentworth participated in the Directors NQDCP during 2024.

REPORT OF THE AUDIT COMMITTEE

This report by the Audit Committee is required by the rules of the SEC. It is not to be deemed incorporated by reference by any general statement that incorporates by reference this Proxy Statement into any filing under the Securities Act or the Exchange Act, and it is not to be otherwise deemed filed under either such Act.

The Audit Committee is currently comprised of six members, each of whom is an "independent director," as defined by Section 303A of the NYSE Listed Company Manual. Each of the members of the Audit Committee is financially literate and qualifies as an "audit committee financial expert" under federal securities laws. The Audit Committee's purposes are to assist the Board in overseeing: (a) the quality and integrity of our financial statements; (b) the qualifications and independence of our independent auditors; and (c) the performance of our internal audit function and independent auditors.

In carrying out its responsibilities, the Audit Committee has:

Based on the review and discussions noted above and our independent auditors' report to the Audit Committee, the Audit Committee recommended to the Board of Directors that our audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

AUDIT FEES

Aggregate fees billed to us for the fiscal year ended December 31, 2024 and for the fiscal year ended December 31, 2023 by PricewaterhouseCoopers LLP are as follows:

Audit Fees. This category includes the aggregate fees billed for professional services rendered for the audit of our consolidated financial statements and internal control over financial reporting for the fiscal years ended December 31, 2024 and December 31, 2023, for the reviews of the financial statements included in our Quarterly Reports on Form 10-Q during 2024 and 2023, and for services that are normally provided by the independent auditors in connection with statutory and regulatory filings or engagements for the relevant fiscal years.

Audit Matters

Tax Fees. This category includes the aggregate fees billed in each of the last two fiscal years for professional services rendered by the independent auditors for tax compliance, tax planning and tax advice.

All Other Fees. This category includes the aggregate fees billed in each of the last two fiscal years for products and services provided by the independent auditors that are not reported above under "Audit Fees," "Audit-Related Fees," or "Tax Fees."

The Audit Committee reviews and pre-approves audit and non-audit services performed by the Company's independent auditors as well as the fees charged for such services. The Audit Committee has considered whether the provision of non-audit services by PricewaterhouseCoopers LLP was compatible with maintaining the firm's independence. The Audit Committee may delegate pre-approval authority for such services to one or more members, whose decisions are then presented to the full Audit Committee at its scheduled meetings. In 2024 and 2023, all of the audit and non-audit services provided by our independent auditors were pre-approved by the Audit Committee in accordance with the Audit Committee Charter.

Proposal 2 - Ratification of the Appointment of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors has evaluated the qualifications, performance and independence of PricewaterhouseCoopers LLP and has appointed PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for the year ending December 31, 2025. Although the Company is not required to submit the appointment of its independent registered public accounting firm to the stockholders for ratification, the Board of Directors believes that it is important to do so as a matter of good corporate governance. This proposal asks you to ratify this selection. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so. In addition, they will be available to respond to appropriate questions from stockholders.

Pursuant to its charter, the Audit Committee has sole and direct responsibility for the appointment, compensation, retention and oversight of the work of the independent registered public accounting firm engaged by the Company. The Audit Committee will consider the results of the stockholder vote on ratification, but will exercise its judgment, consistent with its responsibilities under its charter, with respect to the appointment and retention of the Company's independent registered public accounting firm.

BOARD RECOMMENDATION

The Board of Directors recommends a vote "FOR" ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm.

Performance Goals and Results

Executive Summary

Our compensation programs reflect our commitment to pay for performance and align the interests of our key employees with those of our stockholders. Executive compensation plans are designed to support the Company's annual financial goals and long-term strategic plan, as well as to promote stockholder value creation. A significant portion of the compensation packages of our Executives is at-risk pay earned based on specific financial and operational achievements. During 2024, the Company:

Throughout 2024, our compensation program performed as designed, allowing the Company to attract new talent, retain important members of management and reward key members of management appropriately for performance.

Compensation Matters

Compensation Design and Market Positioning

The Company's compensation programs are designed to attract, retain, motivate and reward the Executives responsible for leading the business in a manner that directly aligns the Executives' interests with those of the Company's stockholders. To accomplish these objectives, the Committee sets each of the primary components of the Company's executive compensation program (base salary, short-term cash incentive and long-term equity-based incentives) at a market-competitive rate, which is determined by reference to the approximate median of the relevant peer group (the Industry Specific Peer Group for the CEO and CFO, and the Survey Peer Group for the other NEOs, each as identified below), resulting in each Executive's total compensation opportunity being set at approximately the median of the relevant peer group's total pay for executives with similar positions and responsibilities. The Committee does not employ a mechanical process based on external compensation data, however, as other considerations such as time in position, role, individual performance and succession within the Company are considered. As data for the relevant peer group fluctuates or the peer group members are updated to reflect changes in the market, the Committee may make adjustments in one or more components of compensation to more closely align with market. The Committee and, with respect to the President and CEO, the Board of Directors, have full discretion to choose the elements of executive compensation that the Executives will be paid or will be eligible to eaeach year and to adjust the proportion of total compensation opportunity that each element provides. Company performance, market data, individual performance, executive succession, hiring and retention needs and internal equity among our Executives' compensation packages have been the primary factors considered in decisions to change compensation materially.

Peer Group and Market Data

Annually we obtain an analysis of compensation market data to assist in setting pay opportunities for our Executives for the following year. Compensation of the Executives is compared to the pay opportunities provided to executives holding comparable positions at companies with which we compete for business and for talent. The companies used for this comparison are recommended by the Company and the Committee's compensation consultant and approved by the Committee. Both peer groups are reviewed annually and updated, if necessary, to ensure their appropriateness given any market changes. The companies used to develop 2024 executive compensation are listed below. After reviewing the companies in the prior year's comparator groups against the criteria historically used to determine appropriate peers, the Committee determined that no changes were warranted.

Compensation Matters

Pay and Performance

Although target compensation for each of our Executives is established at the beginning of each year with reference to the approximate median of the relevant peer group, each Executive's actual compensation each year may be above or below the target level based on individual, business unit and overall Company performance, as well as changes in the price of the Company's common stock. The Committee believes that the Company's compensation program has been successful in aligning pay levels with the performance of the Company over time. The chart below illustrates the relationship between the total compensation of the CEO and the aggregate compensation of the other NEOs (as set forth in the Summary Compensation Table but excluding changes in pension value) and the Company's Adjusted EBITDA. Adjusted EBITDA is used by the Company as a performance measure for both the MIP and the long-term incentive program because it measures the operational effectiveness of the whole organization while adjusting out those charges or credits that are unrelated to core operations.

Key Compensation Practices

Below are certain of the Company's executive compensation practices that we believe are instrumental in achieving the Company's compensation goals while mitigating risk and maintaining sound compensation practices.

Role of our Stockholders

Our stockholders play an important advisory role in determining the appropriateness of the compensation paid to our Executives. At the Annual Meeting of Stockholders on May 23, 2024, over 91% of the shares represented and entitled to vote at the Annual Meeting were voted to approve the compensation of the Company's Named Executive Officers, as discussed and disclosed in the 2024 Proxy Statement. After considering the results of this advisory vote on executive compensation, as well as the advisory votes in 2023 and 2022 that were each approved by over 90%, the Committee concluded that the compensation paid to our Named Executive Officers and the Company's overall pay practices enjoy strong stockholder support. Going forward, future advisory votes on executive compensation, including the vote on the executive compensation described in this Proxy Statement will serve as an additional tool to guide the Board and the Committee in evaluating the alignment of the Company's executive compensation program with the interests of the Company and its stockholders.

Note that at the Annual Meeting of Stockholders on May 24, 2023, our stockholders expressed a preference that advisory votes on executive compensation occur every year. Consistent with this preference, the Company is maintaining its practice of an advisory vote on executive compensation once every year. The next required vote on the frequency of stockholder votes on executive compensation will occur at the 2029 Annual Meeting of Stockholders.

Compensation Matters

Role of the Compensation and Management Development Committee

The Committee is responsible for establishing the Company's general compensation philosophy and working with management to develop all compensation programs, including the equity compensation programs in which the executive officers participate. The Committee works to ensure that the Company's practices, policies and programs, including its integrated talent management process and its Company Culture and Engagement Initiatives, link pay to performance, encourage an appropriate degree of risk-taking, are consistent with the Company's objectives of attracting, retaining, rewarding and motivating key employees, and align the interests of key employees with those of stockholders. The Committee's annual process for determining the compensation of each NEO is depicted below.

Compensation Process

In addition to setting compensation levels, the Committee annually reviews the Company's compensation programs and assesses whether any risks arising from such practices, policies and programs are reasonably likely to have a material adverse effect on the Company. The Committee also reviews, evaluates and approves the Company's health and welfare plan offerings and the Company's retirement plans to ensure their alignment with the market, effectiveness in attracting and retaining talent and cost effectiveness. The Committee is also responsible for

reviewing the Company's culture programs and integrated talent management processes to assess the success of these programs in facilitating the Company's short-and long-term objectives. The Committee directs the annual succession planning process for executive officers and facilitates the Board's review and approval of the President and CEO's succession plan. The Committee also annually reviews compliance with executive shareholding requirements and monitors any application of the Company's clawback policy.

Role of Compensation Consultants

The Committee retained WTW to act as the Committee's independent consultant on executive compensation and benefits throughout 2024. The mandate of the compensation consultant is to work for the Committee in its review of executive compensation practices and programs, including assessing the overall competitiveness of pay levels and program design, and providing updates on market trends and technical considerations. The Committee instructed the compensation consultant to compile and provide data on both total pay and individual elements of compensation among companies in the peer groups, as well as trends in compensation practices that they observed within the peer groups and generally among public companies. The Committee does not rely on the compensation consultant to recommend specific levels of total pay or any specific element of compensation to our Executives (other than the CEO for whom they make a recommendation); such recommendations are developed by management based on information provided by the compensation consultant and then presented to the Committee for consideration. Representatives of WTW attended each of the five Committee meetings in 2024 at the Committee's request and were available to provide information to the Committee as questions and issues arose. The Committee completes an assessment of the compensation consultant annually. The Committee determined that the compensation consultant is independent after consideration of the SEC's independence factors.

Role of Executive Officers

The President and CEO and Executive Vice President, Human Resources use the compensation consultant's executive benchmarking data to make recommendations for base pay, MIP targets and LTIP targets for the Executives (other than the President and CEO). The Committee works with the compensation consultant to propose the compensation design and award amounts for the President and CEO to the Board of Directors.

Overview of Executive Compensation Components

The Committee evaluates the alignment between compensation philosophy, plan design and achievement of short and long-term results to determine the components of our Executives' compensation program. We structure the majority of compensation to Executives as performance-based compensation. Our 2024 executive compensation program consisted of the compensation components set forth in the table below.

Each of these elements is discussed further below, as well as the methodology used for setting the amount of each type of compensation.

Base Salary

The Committee generally reviews and makes any adjustments to base salaries in connection with changes in position and on a periodic basis that is generally twelve months after the most recent adjustment for the Executive. As shown in the table below, in 2024 the Committee approved base salary increases for the Executives ranging from no increase to 6.2%, with Mr. Doss receiving no increase for 2024 as the Committee decided to make a higher percentage of his compensation incentive or "at risk" compensation. Other base salary increases were based upon each Executive's performance, scope of responsibilities, market data for executives with similar positions and responsibilities, and internal equity considerations. Such increases became effective as of January 1, 2024.

Short-Term Cash Incentive

The Company's short-term cash incentive opportunity under the MIP rewards the achievement of specified annual financial goals. For 2024, the financial measures used to set such financial goals were 2024 Adjusted EBITDA and 2024 Cash Flow Before Debt Reduction, each weighted 50% in the calculation. The Committee chose these financial metrics because they are well understood objective targets and have a direct link to the Company's annual business plan. The degree to which MIP pays out varies both up and down based on business performance (up to a maximum of 200% of target), as reflected in the following chart.

2024 MIP Performance Goals

Adjustments to MIP target levels are made periodically, taking into consideration the relevant peer group, the CEO's recommendations (for Executives other than himself) and input from the compensation consultant. The annual incentive target (as a percentage of base salary) for each of the Executives for 2023 and 2024 is set forth below:

Compensation Matters

Short-Term Cash Incentive Payouts for 2024.Cash incentive payouts under the MIP for 2024 for the Executives are shown in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table. The Company's performance with respect to its 2024 Adjusted EBITDA performance goal was 93% of target and with respect to its 2024 Cash Flow Before Debt Reduction performance goal was 81% of target, resulting in a calculated MIP payout at 26% of target.

For more information on the 2024 annual incentive opportunities for the Executives, refer to the "Grants of Plan-Based Awards" table in this Proxy Statement. The column titled "Estimated Future Payouts Under Non-Equity Incentive Plan Awards" provides the estimated payouts for the Executives at threshold, target and maximum performance levels for 2024.

Long-Term Incentives

The Committee has designed the long-term equity incentive program to be consistent with its desire to tie a larger percentage of the Executives' total compensation to Company performance. Accordingly, one-third of the total long-term incentive value is granted in Service RSUs and two-thirds is granted in Performance RSUs. Both Service RSU and Performance RSU grants are intended to retain Executives during a multi-year vesting period and promote equity ownership.

Performance RSUs granted under the long-term incentive program generally vest in full on the third anniversary of the grant date (assuming the Executive has continued in his or her employment by the Company through such date). Service RSUs granted in 2024 vest in three equal tranches on the first, second and third anniversaries of the grant date. Upon death, disability, or involuntary termination without cause, a proportion of the RSUs vests. Upon retirement (as defined in the grant agreement), all of the RSUs vest if the participant continued in the employment of the Company through December 31st of the year in which the grant occurred and subsequently retired and the participant provided written notice to the Company of his or her retirement at least six (6) months prior to the date of termination of employment due to retirement. If the participant is a Vice President or above and did not provide written notice to the Company of his or her decision to retire at least six (6) months prior to the termination of employment due to retirement, then only a portion of the RSUs vest. In the event of a change of control (as defined in the Graphic Packaging Holding Company 2014 Omnibus Stock and Incentive Compensation Plan (the "2014 Plan")), all Service RSUs and earned Performance RSUs vest in full. The number of Performance RSUs considered earned in the event of a change of control is determined based on assumed target performance for the performance period.

Payout of 2021 Grants.In February 2024, the Committee approved the payout of the Performance RSUs granted in 2021 at 200% of target, based on the achievement of the performance goals for the three-year performance period shown below, as adjusted by the relative total shareholder retumodifier.

2021 Long-Term Incentive Program Performance Goals

The Company achieved 3-Year Aggregate 2021 Adjusted EBITDA of $4,532 million (111.6% of target) resulting in a payout of this component at 200%, 3-Year Average 2021 Retuon Invested Capital of 12.48% (107.1% of target) resulting in a payout of this component at 170.9%, and 3-year Organic Revenue Growth of 500.3% resulting a payout of this component at 200%. Overall performance of these performance measures resulted in a combined payout at

Compensation Matters

188.4% of target prior to application of the TSR modifier. The Company's performance with respect to TSR was at the 76.0 percentile, which resulted in a 120.0% payout modifier. Applying the TSR modifier to the Company's 188.4% performance under the performance measures, the payout was 200% of target.

2024 Grants.In February 2024, the Company granted both Service RSUs and Performance RSUs to each Executive, under the long-term incentive program. For Executives, the total number of RSUs granted was set based on a value delivered as a percentage-of-salary formula, with the percentage established based on a review of responsibilities, market data and internal equity considerations. The value determined by the percentage of salary was then converted to the total number of RSUs by dividing the value by the average stock price of the Company's common stock during January 2024. One-third of the total number of RSUs was granted as Service RSUs and two-thirdswas granted as Performance RSUs. The target value of RSUs granted under the long-term incentive program (as a percentage of salary) during 2023 and 2024 for each of our Executives is set forth below:

For the Performance RSUs granted in 2024, the performance goals consist of a preset aggregate 2024 Adjusted EBITDA amount, a 2024 Retuon Invested Capital percentage and an Organic Revenue Growth percentage. The actual 2024 Adjusted EBITDA, 2024 Retuon Invested Capital and Organic Revenue Growth performance goals are not disclosed here, as the Committee believes they constitute sensitive competitive information. The actual goals will be disclosed after payout. The Adjusted EBITDA goal is weighted in the calculation of the Company's annual achievement at 40%, the Retuon Invested Capital percentage goal is weighted in the calculation at 40% and the Organic Revenue Growth goal is weighted at 20%. Total payout is also subject to a relative TSR modifier, which can modify payouts earned up or down by up to 20% (subject to the 200% of target cap). This payout modifier measures the Company's stock performance against other similar companies and helps to more closely align management and stockholders' interests.

Health and Welfare Benefit Plans

The Committee believes that it is necessary to provide health and welfare benefits to promote the well-being of the Company's employees and to remain competitive in the recruitment of high-performing talent. The health and welfare benefit plans are similar to those provided by the Company's peer group companies.

Perquisites

The Company generally does not provide significant perquisites to its Executives, other than Company-initiated relocation benefits (and tax gross-ups with respect thereto) and executive physicals.

Retirement Benefits

Qualified and Non-Qualified Defined Benefit Plans.During 2019 and 2020, the Company settled its liabilities under the GPI U.S. Consolidated Pension Plan (the "Pension Plan") through lump-sum payouts to participants and the purchase of a group annuity contract that transferred the Company's remaining pension benefit obligations to an insurance company. Following completion of these actions, none of the Executives participate in the Company's remaining qualified pension plan, although Messrs. Doss and Yost still have balances in the Company's supplemental executive retirement plans.
